Victron Energy Orion XS Smart (Bluetooth) DC-DC Charger 12/12V 50A 700W

This Victron Energy Orion-XS Smart DC to DC Charger is the single most important modification I have done to my RV. I absolutely love it. Its like putting 800 watts of solar on your roof top with unlimited sun. Seriously, this was a very easy install and this device functions as a charger and power source. It quickly tops off your lithium batteries and gives you an accurate level of charge depending upon how much juice your batteries have. For my application, I had to use 4 gauge wires which were a very tight fit. The connectivity to the app was a snap and I believe Victron is the best in the business, especially for the price! Great product! Would definitely buy again!

Work like a high powered dream. Recommend buying! Victron + SOK Battery System Charging Path Narrative This document describes the wiring layout and rationale for each major charging component in a custom power system installed in a Ford Transit 250 High Roof EcoBoost van. The system includes two SOK SK12V314PH LiFePO4 batteries, a Victron MultiPlus 12/3000, a Victron SmartSolar MPPT 100/30, two Victron Orion XS 12/12-50A DC-DC chargers, and a Cerbo GX for centralized control and monitoring. 1. Alternator Charging Path (DC-DC via Orion XS 50A Chargers) Source: Ford Transit 250's factory 175A Customer Connection Point (CPP). Cable: 15 feet of 2/0 AWG marine-grade cable is used to carry alternator current from the CPP to a protection and distribution system. Breaker: A Blue Sea 120A breaker protects this main charging input, limiting current to protect wiring and components downstream. Bus Bar: From the breaker, 2/0 AWG marine-grade cable continues to a Blue Sea 250A rated positive bus bar. Orion Input Wiring: Two 4 AWG marine-grade wires run from the 250A bus bar to the input terminals of each Victron Orion XS 12/12-50A charger. Grounding: The Orion XS units are grounded using 4 AWG marine-grade wire to a common Blue Sea negative bus bar. Orion Output Wiring: Each Orion’s output is protected with an 80A Blue Sea breaker. From each breaker, 4 AWG marine-grade wire connects the Orion’s output to a second positive bus bar. Purpose: This setup ensures safe, controlled DC-DC charging from the van alternator to the house battery bank. The Orion XS units are managed via DVCC and Ve.Direct Connect to the Cerbo GX, and configured to only turn on when alternator voltage rises above the engine-on threshold, preventing van battery drain. 2. Solar Charging Path (SmartSolar MPPT 100/30) Controller: Victron SmartSolar MPPT 100/30 connected to a solar array (not detailed here). Connection to System: The MPPT’s positive output wire connects to the same positive output bus bar used by the Orion chargers. Ground: MPPT negative output wire connects to the shared negative bus bar. Monitoring: MPPT is VE.Direct connected to the Cerbo GX, enabling DVCC and battery voltage/current telemetry. Purpose: Provides charging from solar independent of engine operation. Integrated into GX for full system coordination. 3. Inverter/Charger Path (Victron MultiPlus 12/3000) Connection: The MultiPlus is wired directly to the main positive bus bar with 4/0 AWG marine-grade cable. Ground: The MultiPlus negative is wired to the main negative bus bar using 4/0 AWG marine-grade cable. 30 Amp fused Shorpower link: Connected to the Inverter with 4/0 AWG Digital Multi-control: Connected to the Victon Cerbo GX with regular RJ45 allows inverter control from the cabin Function: Provides both shore charging and AC inversion. Shore charging current is regulated via the Cerbo GX and DVCC in communication with the SOK BMS. Rationale: 4/0 AWG ensures low resistance paths for high current draw and charging currents. 4. Battery Bank Wiring (SOK SK12V314PH Batteries) Configuration: Two SOK 314Ah LiFePO4 batteries connected in parallel. Wiring: Both batteries are connected to the positive bus bar with 4/0 AWG marine-grade cable. Similarly, both battery negatives are wired to the shared negative bus bar with 4/0 AWG. Monitoring: The SOK BMS communicates via CAN bus to the Cerbo GX, which centrally manages charge voltage and current limits across the system (Orions, MPPT, MultiPlus). 5. Ventilation Fan Control (Temperature-Based) Fans: Two 12V DC fans are installed for compartment cooling. Control: Fans are triggered automatically using temperature relays configured in the Cerbo GX. Purpose: To protect sensitive components (batteries, inverter, DC-DC chargers) from heat buildup, especially during charging. This architecture prioritizes safety, alternator protection, smart BMS-based charging, and full integration with Victron GX for visibility and control. It balances high-capacity charging with efficient heat management and battery health longevity.

This DC Converter is fantastic. I have the 30amp version on my sailboat and enjoy that unit, however I will continue to use this smart 50amp version for all my uses moving forward. The device is smaller, and has ability to control the incoming amperage, and outgoing amperage to fit the use better. The adjustment of amperage has been elemental to success on my boondock RV switching from short power, to truck alternator, to any other DC power source I may plug in. Highly suggest Victron in total and this XS unit specifically.

Yeah, this thing is legit. I originally had gotten the 1212 30, and let me tell you, not being able to customize the amount of amperage going through is no, no, no. This one, being able to completely customize what amperage you're pushing, is so nice. Victron stays quality. Nonetheless, the accessibility was unreal too. Was able to get this overnight in a pinch. Super accurate and really great instructions, compatible with my BlueEddy system powering my Vader battery

I have a 2022 Winnebago Micro Minnie FLX travel trailer with 570 Watts of Solar Panels and a 30-amp Solar Charger charging a single 320-amp LiFePo battery. Since I don’t have much of a footprint on the trailer roof for more solar panels, I decided to install a DC-to-DC Charger so my truck could charge the trailer house battery while I was driving, much like camper vans do with built in DC-to-DC Chargers. After doing hours of research and watching a lot of YouTube videos to find the best charger, I settled on the Victron Orion XS 50-amp DC-to-DC Charger. To say I’m extremely pleased with this Victron Charger would be a huge understatement. It has worked beyond my greatest expectations! One problem I did have to overcome was finding the best way to run the input wiring to the Charger from my 2022 Chevy Silverado 2500HD Diesel truck’s primary battery. I finally settled on using 175-amp Anderson connectors to provide the connection between the truck and the trailer and ran Spartan Power 2-AWG welding cables from the truck battery to the truck side Anderson connector and the same gauge cable from the trailer side Anderson connector to a Joinfworld Heavy Duty 400A Bus Bar Distribution Block near the Victron DC-to-DC charger. From the Distribution Block, I transitioned down to Spartan Power 4-AWG welding cable to make the final connection to the Victron charger. To provide further abrasion/heat protection for the positive and negative cables, I double jacketed both 2-AWG welding cables with 1 layer of GEARit 1-1/2” Heat Shrink Tubing and 1 layer of 1-3/8” Automotive Heat Shrink Braided Sleeving. I also incased the truck side Anderson connector in a Trailer Vision Anderson Connector Plug Cover surface mounting kit and the trailer side Anderson connector in a Trailer Vision Anderson Connector Cover Assembly to provide better dust/water protection. Finally, to provide proper circuit protection, I installed a BOJACK in-Line ANL Fuse Holder with 150-Amp Fuse for the positive cable from the truck battery and 2 Young Marine 60-Amp Circuit Breakers for the positive Input and Output of the Victron Charger. I highly recommend the Victron Orion XS 50-amp DC-to-DC Charger. It operates as advertised and the Victron Connect app makes it very easy to setup the charger for various batteries and battery manufacturer settings and to monitor the status of the charging while driving down the road. I’ve even used my truck to charge the battery while boondocking when the solar panels weren’t providing enough charge on very cloudy days. A very nice bonus!

This is an improved DC to DC converter that is much smaller and runs much cooler than its predecessor. While it is not cheap, it is a Victron component, is robust, well-made and its many features are well documented. It can be connected to your Victron network of other components and displays on the Victron connect app. I use it to charge the lithium battery in my truck camper. I ran a 4-gage wire from the truck battery to an Anderson plug that connects to the truck camper. A bit of a project to set up, but very nice.

Works great. Easy to install.

I strongly urge you NOT to buy anything from InvertersRUs.com. My experience with a faulty Victron Orion XS 12/12-50A device has been an absolute nightmare from start to finish. Here's what happened: 1. Defective Out of the Box I installed the Orion charger on May 28, 2025, and it failed immediately—the same day. It would not deliver the current or voltage it was configured to output. I tested everything meticulously: In charge mode, it maxed out at ~3 amps, even with a deeply discharged lithium battery. The voltage during “Bulk charge” never reached the configured 14.4V—it barely exceeded the input voltage. Nothing overheated, no wiring issues—everything was correct and simple. I thoroughly reviewed the manual, confirmed the setup with a multimeter and app readings, and ran multiple independent tests. The unit simply does not perform as advertised. 2. Three Months of Being Ignored I tried for over three months to get this resolved. Two weeks after I sent the device back, I finally got a callback from someone at InvertersRUs who said, without explanation, that the Orion “works fine.” They refused to share how they tested it, what was done to “fix” it, or any data to prove their claim. I was told to contact technical support. Since then, I left over 30 voicemails, called both support and sales lines, and was repeatedly ignored. I was even told by a salesperson that their support team is “completely overwhelmed” with returns and can’t keep up. 3. They Stall Until the Return Window Expires This is the most egregious part: InvertersRUs intentionally stalled support with slow replies and vague promises until the return period ran out. After doing everything they asked—including extensive testing and submitting a warranty request—they gave me an RMA and asked me to ship the unit (at my cost) for evaluation. I followed their instructions exactly, including emailing and calling to follow up. Once they had the device, they stopped returning calls. Now, even though I'm still willing to pay return shipping, they won’t send it back. I’ve lost the product and my money. 4. Terrible Customer Service and Shady Policies They: Provided no transparency on testing or diagnostics. Repeatedly ignored support requests and voicemails. Offered zero technical guidance other than scripted instructions. Relied on delays and silence to avoid returns and refunds. I’ve never left a negative review before, but this experience was unacceptable. I was patient and fair, yet treated with total indifference. Bottom Line: If you value your time, money, or doing what’s right, DO NOT BUY from InvertersRUs.com. Their service is broken, their return process is a trap, and their support is nonexistent. This company should not be trusted with your business.

Llego en fecha prevista, producto de gran calidad.

Mit einem altmodischen Trennrelais hatte ich immer Probleme. Entweder es hat die Zweitbatterie nicht geladen oder nur wenig. Die Batterie ist schnell kaputt gegangen. Dieses Gerät war schnell zu installieren auch für Laien kein Problem. Bluetooth funktioniert gut, und über die App hat man alle Informationen die man braucht. Zb. Ladezustand der Batterie wie viel wurde geladen .. Verbaut habe ist das Gerät in einen VW T4

Très bon produit , minuscule vis à vis de la gamme précédente et ne chauffe pas énormément malgré des charges à 40A.

I was surprised at how small this unit was compared to my Solar MPPT 100/50 unit (see photo). There are no heatsink fans on the back so I was worried that it would get hot, but it doesn’t. As usual, the VictronConnect app is where it’s at and it’s great to be able to see Solar and Alternator charging from the same place. Really excellent system. Previous to this I was just charging the leisure batteries (4 x 100Ah) from the alternator when solar wasn’t cutting it over winter, but it took forever to charge to 100% and never reached Absorption voltage. This however is a night and day difference in terms of charging in the way it controls the voltage and current when charging. True bulk, absorption, float and storage states means it charges the batteries quickly. Easily three times quicker than using the alternator alone - depending on state of charge. The entire Victron system is highly recommended. A+

Funziona benissimo
